I think I've got this down now. The key was spreading out my crossbars on my Tahoe roof rack. It always worked ok, but they were too close together for me to just put the bow on one hook and swing the transom up onto the other one. I still had to lift the whole yak about 4 ft up. Not anymore. There are a lot of adjustments to make for this system to work properly, but I think I got it figured out now. I almost bought a trailer. I think this will work for now.
